Hello all, first post.

I'll get straight to it. Looking to swap a Renesis into my fc. Like everybody else I'm on to budget. Considered LS and REW swaps but they are a bit out of the budget and I do just want to drive the roller FC that currently resides in my garage.

My goal is as simple of a swap as I can make it, (as simple as putting an engine into a car that was never meant to be in can be).

So, I'm trying to find a work around for all the electronics like ignition control module and other kind of stuff that people find ways of removing when performing a swap. I''m not opposed to buying a tune from Racing Beat if it gets me to where I need.

On to the questions.

I'm in the process of sourcing a 2004 rx8 6 port MT donor vehicle. Can anyone chime in to confirm if I will need to carry over anything related to the ignition, airbag, etc. modules if I get the RB track v2 tune?

Can anyone confirm if I can use a flashed 2004 ECU in other model years of series 1 rx8's sharing the same specs?

Can anyone confirm the part number of the ECU (numbers on the label on the outside case of the ECU) out of a 2004 6 port 6spd manual?

My thought process is that if the RB flash removes the immobilizer function and everything else that ties the ECU to that specific engine regarding electronics, I should be free to use the flashed ECU from a 2004 model year with other model year engine in that series.
